Some of Portland's craft brewers say fluoridation won't affect their beer's taste, but they have concerns about public perception.

Our customers are very concerned about it,” says Jeff Edgerton, brewmaster at Northwest Portland’s BridgePort Brewing. “A lot of them are concerned about whether fluoridation is actually a health concern.”

Edgerton says that as far as the beer industry is concerned, “the problem is, once it’s in the water, it stays in the water.”
